A Northeast Cold Eddy Movement and Its Impact Analysis
The moving process of a cold eddy weather in Liaoning region and its effect were analyzed, with using data observed by automatic station, sounding data and NCEP reanalysis data. The results showed that heavy rain weather in Southern Liaoning Province on August 2th, 2015 was produced in matured stage from the development of the northeast cold eddy . The establish-ment and steady of 500 hPa cold eddy provided favorable large scale circulation background for storm development . The maintain and stable of Hubei high sea resistance led to the cold eddy moves slowly, and made a long time intersec-tion of warm and cool air in Liaoning Province . Low level jet deliveried a lot of unstable energy, heat and momen-tum for heavy rain area . Low-rise shear line and ground convergence line also provided a good dynamic lifting effect for the heavy rains triggered .
